NEET Physics Speed & Velocity MCQ Question
Consider a velocity-time graph that shows motion with constant acceleration, where the object changes direction at a certain point. Which of the following correctly describes the behavior of velocity at the point of direction change?
Velocity becomes zero before reversing direction.
Velocity remains constant and non-zero while changing direction.
Velocity increases as the direction changes.
Velocity decreases continuously without becoming zero.
Correct Answer
Detailed Explanation
In the NCERT context, when an object changes direction, its velocity must momentarily become zero before reversing, as indicated by the velocity-time graph for motion with negative acceleration.
